Improve documentation for importing from GitHub Enterprise
It's hard to find the instructions for how to make GitLab import from GitHub Enterprise.
Searching for different terms on Google didn't turn it up: "github enterprise importer gitlab":
I suggest we improve https://docs.gitlab.com/ce/integration/github.html to make it clear:
- Use terms to improve SEO that make it very clear how to set things up for for GitHub Enterprise
- Make it clear you have to configure GitLab to import from either GitHub.com or a GitHub Enterprise host
- Have clearer instructions: "If you want to import from GitHub Enterprise, do these steps". Right now the instructions are muddled with self-signed certs, GitHub.com, etc.
